I just had a meeting with a MD that I volunteer for in his organization to discuss about him writing me a LOR for my medschool application. He asked me about my grades and MCAT (sGPA 3.38, 31L) and they are mediocre so I explained that I come from a nontrad background. He was very disappointed and said that he's not confidant that I'll be a doctor and said that he will not be comfortable with me being with patients. But... he agreed to write me the LOR. So, I don't think he's going to write me a good one so how do I decline his offer to write the LOR?
